 * @projectDescription Easy element scrolling using jQuery.
 * Compatible with jQuery 1.2.1, tested on Firefox 2.0.0.7, and IE 6, both on Windows.
 *
 * @author Ariel Flesler
 * @version 1.2.4
 *
 * @id jQuery.fn.scrollTo
 * @param {String|Number|DOMElement|jQuery} target Where to scroll the matched elements.
 *	  The different options for target are:
 *		- A number position (will be applied to all axes).
 *		- A string position ('44', '100px', '+=90', etc ) will be applied to all axes
 *		- A jQuery/DOM element ( logically, child of the element to scroll )
 *		- A string selector, that will be relative to the element to scroll ( 'li:eq(2)', etc )
 *		- A hash { top:x, left:y }, x and y can be any kind of number/string like above.
 * @param {Object} settings Hash of settings, optional.
 *	 @option {String} axis Which axis must be scrolled, use 'x', 'y', 'xy' or 'yx'.
 *	 @option {Number} speed The OVERALL length of the animation.
 *	 @option {String} easing The easing method for the animation.
 *	 @option {Boolean} margin If true, the margin of the target element will be deducted from the final position.
 *	 @option {Object|Number} offset Add/deduct from the end position. One number for both axis or { top:x, left:y }
 *	 @option {Boolean} queue If true, and both axis are given, the 2nd axis will only be animated after the first one ends.
 *	 @option {Function} onAfter Function to be called after the scrolling ends.
 *	 @option {Function} onAfterFirst If queuing is activated, this function will be called after the first scrolling ends.
 * @return {jQuery} Returns the same jQuery object, for chaining.
 *
 * @example $('div').scrollTo( 340 );
 *
 * @example $('div').scrollTo( '+=340px', { axis:'y' } );
 *
 * @example $('div').scrollTo( 'p.paragraph:eq(2)', { speed:500, easing:'swing', queue:true, axis:'xy' } );
 *
 * @example var second_child = document.getElementById('container').firstChild.nextSibling;
 *			$('#container').scrollTo( second_child, { speed:500, axis:'x', onAfter:function(){
 *				alert('scrolled!!');
 *			}});
 *
 * @example $('div').scrollTo( { top: 300, left:'+=200' }, { offset:-20 } );
 *
 * Notes:
 *  - jQuery.scrollTo will make the whole window scroll, it accepts the same parameters as jQuery.fn.scrollTo.
 *  - The plugin no longer requires Dimensions.
 *	- If you are interested in animated "same-page-scrolling" using anchors, check http://jquery.com/plugins/project/LocalScroll.
 *	- The option 'margin' won't be valid, if the target is an absolute position.
 *	- The option 'queue' won't be taken into account, if only 1 axis is given.
